    adc0804 with 89s52, can't understand the code.

    Dear diego, that is what i had assumed, but working backwards manually doens't match properly. for example : at 100 deg C, the resistance of the PT-100 is 138.4ohm, and working backwards using that equation it give about 150+ ohms. Are you aware how to manually convert the ADC 0804 o/p to...

    adc0804 with 89s52, can't understand the code.

    Dear all, I am working ona project where i sense temp using PT-100, voltage comparator conditions the voltage to be between cmos limits. Following this adc 0804 converts A to D, and feeds to the micro-controller. the following is the cade, working fine! but i cannot understand a particular...
